C. Construction Methods. The steel posts shall be set true to line and grade in concrete bases.

D. The distances between posts in any section shall be uniform, but shall not exceed the following spacing:

 1. Tangent sections and curves down to five hundred (500) foot radius: not more than ten (10) feet;

 2. Curves five hundred (500) foot radius to two hundred (200) foot radius: not more than eight (8) feet;

 3. Curves two hundred (200) foot radius to one hundred (100) foot radius: not more than six (6) feet;

 4. Curves one hundred (100) foot radius: not more than five (5) feet.

E. A minimum of six (6) inches of concrete shall be provided below the bottom of each post. End posts, pull posts, corner posts, and gate posts shall have a concrete base at least ten (10) inches in diameter. Bases for line posts shall be at least eight (8) inches in diameter.

F. Pull posts shall be provided at five hundred (500) foot maximum intervals. Changes in line of thirty (30) degrees or more shall be considered as corners.

G. Fence fabric shall be placed on the roadway side of posts unless otherwise specified. The fabric shall be placed approximately one (1) inch above the ground, and on a straight grade between posts by excavating high points of the ground. Filling depressions will be permitted only upon approval of the City Engineer.

H. The fabric shall be stretched taut and securely fastened to the posts. Fastening to end, gate, corner, and pull posts shall be with stretcher bars and metal bands spaced at one-foot intervals. The fabric shall be cut and each span fastened independently at all pull and corner posts. Fastening to line posts shall be with tie wire, metal bonds, or other approved methods at fourteen (14) inch intervals. The top edge of fabric shall be attached to the top rail at approximately twenty four (24) inch intervals. The bottom tension wire shall be attached to the fabric with tie wires at twenty four (24) inch intervals and shall be secured to the end or pull posts with brace bands.

3.18.015 WOOD FENCE SPECIFICATIONS.

All posts shall be sound and free from all decay, splits, multiple cracks, or any other defect which would weaken the posts or otherwise cause them to be structurally unsuitable for the purpose intended.

D. The maximum distance between posts in any section shall not exceed eight (8) feet. The top and bottom railings shall be securely fastened to the posts with galvanized nails or other acceptable means. Changes in line of thirty (30) degrees or more shall be considered as corners. A minimum of six (6) inches of concrete shall be provided below the bottom of each post. End posts, corner posts, and gate posts shall have a concrete base at least twelve (12) inches in diameter. Bases for line posts shall also be twelve (12) inches in diameter.

E. Fence slats shall be placed on the roadway side of posts unless otherwise specified. The slats shall be placed approximately one (1) inch above the ground, and on a straight grade between posts by excavating high points of the ground. Filling depressions will be permitted only upon approval of the City Engineer. The slats shall be sound and free from all major decay or defects which would weaken or otherwise cause them to be unsuitable for fence slats. Fastening to top and bottom railings shall be done with two (2) galvanized nails at both the top and bottom rail.
